[GIT PULL] target fixes for v4.5-rc4

[Nicholas A. Bellinger]

Hi Linus,

Here are the target-pending bug-fixes for v4.5-rc4.

Please go ahead and pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git master

This includes the long awaited series to address a set of bugs around
active I/O remote-port LUN_RESET, as well as properly handling this same
case with concurrent fabric driver session disconnect -> reconnect.

Note this set of LUN_RESET bug-fixes has been surviving extended testing
on both v4.5-rc1 and v3.14.y code over the last weeks, and is CC'ed for
stable as it's something folks using multiple ESX connected hosts with
slow backends can certainly trigger.

The highlights also include:

  - Fix WRITE_SAME/DISCARD emulation 4k sector conversion in target/iblock
    (Mike Christie)
  - Fix TMR abort interaction and AIO type TMR response in qla2xxx target
    (Quinn Tran + Swapnil Nagle)
  - Fix >= v3.17 stale descriptor pointer regression in qla2xxx target
    (Quinn Tran)
  - Fix >= v4.5-rc1 return regression with unmap_zeros_data_store
    new configfs store handler (nab)
  - Add CPU affinity flag + convert qla2xxx to use bit
    (Quinn + HCH + Bart)

Thank you,

--nab
